Ah, that's because us engineers don't have a sense of humor. I thought you knew that.
Here is one:
A Engineer gets home from work and sees a note on the fridge from his wife. “This isn’t working, I’m at my moms”. he opens the fridge and checks the light, then grabs a beer and feels it cold. The engineer thinks to himself. “The fridge works fine”.
Here is one for your side:
Doctors at a hospital in Brooklyn, New York have gone on strike. Hospital officials say they will find out what the Doctors' demands are as soon as they can get a pharmacist over there to read the picket signs!
